  • blind nuts having tube-shaped portions of different lengths have to be prepared based on the thickness of the member.
  • a type of blind nut is desired that can be mounted without any problem on members such as panels having a wide range of thicknesses.
  • a blind nut is disclosed in Japanese Laid-Open Utility Model Publication No. 58-162312 which has an internal threaded portion, a tube-shaped portion, and a flange.
  • the tube-shaped portion is inserted into a hole in a panel and buckled to secure the panel between the flange and the buckled tube-shaped portion.
  • the diameter of the hole in the tube-shaped portion gradually narrows from the flange to the internal threaded portion. Because the thickness of the tube-shaped portion of the blind nut in Japanese Laid-Open Utility Model Publication No. 58-162312 gradually increases from the flange to the internal threaded portion, the portion near the flange is more easily deformed. As a result, the blind nut in Patent Document 1 can be secured to a panel of any thickness.
  • the location where the buckling of the tube-shaped portion takes place depends on the thickness of the panel. Therefore, when the panel is thick, the buckling occurs from a relatively thick part of the tube-shaped portion, and the load increases when the blind nut is mounted. A buckling abnormality is more likely to occur when the buckling occurs in a relatively thick part of the tube-shaped portion, and the diameter of the tube-shaped portion does not expand sufficiently.
  • a blind nut is disclosed in Japanese Laid-Open Patent Publication No. 9-242728 which has a shank, a flange, and a threaded bore.
  • the bore in a first portion of the shank near the flange has a large diameter
  • a second portion has an intermediate diameter
  • the bore in a third portion far from the flange has a small diameter.
  • the first portion of the shank is deformed to secure a first body between the first portion and the flange
  • the second portion is deformed to secure a second body between the first portion and the second portion.
  • the first portion and the second portion can be gradually deformed to secure two bodies (members) with space between them.
  • Japanese Laid-Open Patent Publication No. 9-242728 a different pull rod has to be used when the first body is secured than when the second body is secured. This makes the fastening operation more complicated.
  • the invention in Japanese Laid-Open Patent Publication No. 9-242728 is used to mount two bodies with space between them. It cannot fasten members with a wide range of thicknesses.
  • blind nut that can be mounted without any problem on members such as panels having a wide range of thicknesses. Also, a blind nut is desired that can be reliably mounted on a member by sufficiently widening the diameter of the tube-shaped portion.

  • a purpose of the present invention is to provide one type of blind nut that can be mounted without any problem on members such as panels having a wide range of thicknesses.
  • Another purpose of the present invention is to provide a blind nut that can be reliably mounted on a member by sufficiently widening the diameter of the tube-shaped portion.
  • the present invention includes a tube-shaped portion (diameter-widened portion) which has a thick portion and a thin portion.
  • a tube-shaped portion diameter-widened portion
  • the diameter of the thin portion is widened.
  • the diameter of the thick portion is widened. This prevents any buckling mishap, even when the blind nut is mounted on a member such as a thin sheet.
  • a first aspect of the present invention is related to a blind nut including an internal threaded portion having internal threading on the inside, a hollow tube-shaped portion adjacent to the internal threaded portion, and a flange with an opening provided at the opposite end of the internal threaded portion.
  • the internal threaded portion and the tube-shaped portion are inserted into a mounting hole in a member, and a part of the tube-shaped portion is plastically deformed so as to enlarge the diameter, thereby securing the member between the deformed expanded diameter portion and the flange, and mounting the nut on the member.

  • the blind nut is reliably secured to a member without any buckling mishap. Also, because the outer diameter of the expanded diameter portion can be sufficiently enlarged by plastic deformation, the securing strength is increased, and the nut is reliably secured.
  • a part of the second tube-shaped portion is plastically deformed so as to enlarge the diameter
  • the deformation of the second tube-shaped portion elastically deforms the first tube-shaped portion so as to enlarge the diameter
  • the member is secured between the flange and the expanded diameter portion obtained by plastically deforming the first tube-shaped portion and the second tube-shaped portion. Because the thin second tube-shaped portion buckles under a low load and its diameter expands, a buckling mishap is less likely to occur. Because the diameter of the thick first tube-shaped portion is pulled by the thin second tube-shaped portion and its diameter expands, a buckling mishap is less likely to occur.
  • the internal threaded portion, the first tube-shaped portion, and the second tube-shaped portion have the same outer diameter.

  • the internal threaded portion and the tube-shaped portion are inserted into a mounting hole in the member, a part of the second tube-shaped portion is plastically deformed so as to enlarge the diameter, the deformation of the second tube-shaped portion plastically deforming the first tube-shaped portion so as to enlarge the diameter, and the member is secured between the flange and the expanded diameter portion obtained by plastically deforming the first tube-shaped portion and the second tube-shaped portion, thereby mounting the blind nut on the member.
